How to overide altsyncram instantiation parameter ?

We do instanciate the altsyncram component in our VHDL design without the mapping for the ram_block_type generic parameter so Quartus retains the default value (AUTO).

How can we instruct the tool to map ram_block type to a specific value for a specific instance in the design ?

I have tried the "set_parameter -name RAM_BLOCK_TYPE "\"MLAB\"" -to "...|ALTSYNCRAM"" in the .qsf but without any success and cannot figure out why it is not used and applied by Quartus.

Is it the right way of doing it ? If so, what is the precise syntax ? If not, please let me know how.

Thanks a lot for your support!
